I did a OCLT test actually. My FC at midnight last night was 4.0 and CC was 0. It was the same thing for both at 9am. It just started looking cloudy last night when I came home.
Good job! Since your FC was on the low side, you might want to raise it up and try the OCLT again tonight. I have seen low FC OCLT tests be 0 change, and still have algae. You won't be hurting anything, and it will help eliminate (or not) organisms being your problem.
Let us know your CH level. Also, what is your chlorine source?
It would be helpful if you entered your pool/equipment details in your sig.
